IMPROVEMENT IN CORN-PLANTER S.

Specification forming part of Letters Patent No. 154,507, dated August25, 1874; application filed March 21, 1874.

. To all whom it may concern:

Be it known that we, SAMUEL J. MILLER and LUNA WRIGHT, of Economy, inthe county of Wayne and State of Indiana, have invented a new andvaluable Improvement in Corn-Drills; and we do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawingsmaking a part of this specification, and to the letters and figures ofreference marked. thereon.

Figure 1 of the drawings is a representation of a plan view of ourcorn-drill, and Fig. 2 is a sectional view of the same. Fig. 3 is adetail view.

This invention has relation to machines for planting corn; and itconsists in a revolving dropper, which is removably secured on a shaftwhich is driven from the transporting-wheel of the machine, and which isapplied between two beveled arches, which constitute the stationaryparts of a hopper-bottom; also, in a stationary wire discharger, incombination with a revolving dropper, whereby the kernels of corn aredischarged from the cells in said dropper over the upper end of atubular guide, as will be hereinafter explained.

In the annexed drawings, A designates the frame of the machine; B, thetransportingwheel, and C O the handles or stilts. The axle a of thewheel B carries a beveled spurwheel, b, on one end, which engages with asimilar wheel, I), on a longitudinal shaft, 0. This shaft 0 has its endbearings in brackets which are secured to one side of the frame A, andit communicates rotary motion to the dropper D through the medium of thetwo spur-wheels d d. The wheel 61 is keyed on a horizontal shaft, 0, onthe square portion of which the dropper D is applied. Shaft c has itsbearings in boxes which are secured upon the frame A, and is locatedbetween two cross-pieces, ff. The dropper D is of circular form, havingin its periphery a number of seed-cells, 9, arranged at proper distancesapart. There is also a groove in the periphery of the dropper, whichintersects the axes of all the cells g, and above the plane of frame Athis groove receives a wire, h. One end of the wire it is secured to thecross-bar f, and the other is secured to the upper end of a seed-tube,E, which is secured to the back of a tooth, F. At the point fordischarging the seed into the tube E the wire h is set off from theperiphery of the dropper, so as to insure the discharge of the grainsfrom the cells as they successively move around. At all other points thewire Itv lies on the bottoms of the cells. The dropper can be removedfrom its shaft 0, and it is applied between two arches, J J, which areconstructed with inwardly-beveled surfaces, which will direct the cornin the hopper H upon the dropper. The seed is prevented from crowdingout of the hopper by means of two rub-. ber wipers, j j, which aresecured upon the cross-bars f f, so that their free edges press againstthe periphery of the dropper. wipers keep back the grains, and at thesame time prevent them from being broken. 7c 70 designatecovering-blades.

What we claim as new, and desire to secure by Letters Patent, is p 1.The grooved revolving seed-dropper D,

having a wire discharger 71-, applied to it, substantially as described.I

2. The revolving dropper D, removably applied on its shaft 0, incombination with the two beveled arches J J and the hopper H,substantially as described.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two Witnesses.
